* CER = Constant Exchange Rate, representing growth calculated as if the exchange rates had remained unchanged from those used in 2022. CER is a non-GAAP measure.

• Net product revenues increased 32% and 39% at actual currency during the three and twelve months ended December 31, 2023, respectively, compared to the same periods in 2022, and 30% and 39% at CER, respectively. The increases are primarily due to increased patients on our commercial TTR therapies driven by the launch of AMVUTTRA in the third quarter of 2022 as well as increased patients on GIVLAARI and OXLUMO therapies.

Net Revenues from Collaborations

• Net revenues from collaborations increased 8% and 305% during the three and twelve months ended December 31, 2023, respectively, as compared to the same periods in 2022, primarily due to revenue recognized under our Collaboration and License Agreement with Roche, as executed in July 2023, and revenue recognized under our Novartis Collaboration Agreement associated with the achievement of specified commercialization and regulatory milestones.

Operating Expenses

	Three Months Ended December 31,								Twelve Months Ended December 31,
(In thousands)		2023				2022				2023				2022

Non-GAAP selling, general and administrative expenses	$	175,214			$	184,521			$	671,239			$	632,170

Cost of Goods Sold

• Cost of goods sold as a percentage of net product revenues increased during the three and twelve months ended December 31, 2023, respectively, as compared to the same periods in 2022, primarily due to increased volume and rate of royalties payable on net sales of AMVUTTRA associated with tiered royalty percentages, in addition to increased excess and obsolete charges primarily due to canceling manufacturing commitments and the impairment of ONPATTRO inventory that had been manufactured for future demand associated with the ATTR amyloidosis with cardiomyopathy indication for patisiran for which we did not receive regulatory approval.

Research & Development (R&D) Expenses

• GAAP and non-GAAP R&D expenses increased during the three and twelve months ended December 31, 2023, compared to the same periods in 2022, primarily due to increased headcount and infrastructure expenses to support our R&D pipeline, development expenses associated with the KARDIA-1 and KARDIA-2 zilebesiran Phase 2 studies, and manufacturing and research related expenses associated with our pre-clinical and developmental activities. GAAP R&D expenses further increased during the twelve month period due to increased stock-based compensation expense related to the accounting for certain performance-based awards during the period.

Selling, General & Administrative (SG&A) Expenses

• GAAP and non-GAAP SG&A expenses decreased during the three months ended December 31, 2023, compared to the same period in 2022, primarily due to increased legal expenses in 2022 associated with the Patent Infringement Lawsuits we filed in March 2022 and the Department of Justice investigation, which closed in August 2023, and increased expenses in support of the global launch of AMVUTTRA in the third quarter of 2022.
• GAAP and non-GAAP SG&A expenses increased during the twelve months ended December 31, 2023, compared to the same period in 2022, primarily due to increased headcount and other strategic investments in support of the global launch of AMVUTTRA and other expenses to support our strategic growth.

Other Financial Highlights

• Cash, cash equivalents and marketable securities were $2.44 billion as of December 31, 2023, compared to $2.19 billion as of December 31, 2022, with the increase primarily due to the receipts of a $310 million upfront payment from Roche in connection with our partnership to co-develop and co-commercialize zilebesiran, a $100 million payment from Regeneron in connection with the achievement of certain criteria during early clinical development for our CNS program, ALN-APP, and nearly $150 million from employee option award exercises, offset by our operating loss for the year.

A reconciliation of our GAAP to non-GAAP results for the current quarter is included in the tables at the end of this press release.

2024 Financial Guidance

Full year December 31, 2024 financial guidance consists of the following:

Combined net product revenues for AMVUTTRA, ONPATTRO, GIVLAARI and OXLUMO1	$1,400 million – $1,500 million
Net Product Revenue Growth vs. 2023 at reported Fx rates1	13% – 21%
Net Product Revenue Growth vs. 2023 at constant exchange rates*	13% – 21%
Net revenues from collaborations and royalties	$325 million – $425 million
GAAP R&D and SG&A expenses	$1,900 million - $2,050 million
Non-GAAP R&D and SG&A expenses2	$1,675 million – $1,775 million
1 Uses January 31, 2024 FX rates including: 1 EUR = 1.08 USD and 1 USD = 147 JPY
2 Primarily excludes $225-$275 million of stock-based compensation expense from estimated GAAP R&D and SG&A expenses.
* CER = Constant Exchange Rate, representing growth calculated as if the exchange rates had remained unchanged from those used in the twelve months ended December 31, 2023. CER is a non-GAAP measure.

Use of Non-GAAP Financial Measures

This press release contains non-GAAP financial measures, including expenses adjusted to exclude certain non-cash expenses and non-recurring gains outside the ordinary course of the Company’s business. These measures are not in accordance with, or an alternative to, GAAP, and may be different from non-GAAP financial measures used by other companies.

The items included in GAAP presentations but excluded for purposes of determining non-GAAP financial measures for the periods presented in this press release are, as applicable, stock-based compensation expenses, realized and unrealized (gains) losses on marketable equity securities and loss on the extinguishment of debt. The Company has excluded the impact of stock-based compensation expense, which may fluctuate from period to period based on factors including the variability associated with performance-based grants for stock options and restricted stock units and changes in the Company’s stock price, which impacts the fair value of these awards. The Company has excluded the impact of the realized and unrealized (gains) losses on marketable equity securities because the Company does not believe these adjustments accurately reflect the performance of the Company’s ongoing operations for the period in which such gains or losses are reported, as their sole purpose is to adjust amounts on the balance sheet. The Company has excluded the loss on the extinguishment of debt because the Company believes the item is a non-recurring transaction outside the ordinary course of the Company’s business.

Percentage changes in revenue growth at CER are presented excluding the impact of changes in foreign currency exchange rates for investors to understand the underlying business performance. The current period’s foreign currency revenue values are converted into U.S. dollars using the average exchange rates from the prior period.

The Company believes the presentation of non-GAAP financial measures provides useful information to management and investors regarding the Company’s financial condition and results of operations. When GAAP financial measures are viewed in conjunction with non-GAAP financial measures, investors are provided with a more meaningful understanding of the Company’s ongoing operating performance and are better able to compare the Company’s performance between periods. In addition, these non-GAAP financial measures are among those indicators the Company uses as a basis for evaluating performance, allocating resources and planning and forecasting future periods. Non-GAAP financial measures are not intended to be considered in isolation or as a substitute for GAAP financial measures. A reconciliation between GAAP and non-GAAP measures is provided later in this press release.

About ONPATTRO^® (patisiran)

ONPATTRO is an RNAi therapeutic that is approved in the United States and Canada for the treatment of adults with hATTR amyloidosis with polyneuropathy. ONPATTRO is also approved in the European Union, Switzerland and Brazil for the treatment of hATTR amyloidosis in adults with Stage 1 or Stage 2 polyneuropathy, and in Japan for the treatment of hATTR amyloidosis with polyneuropathy. ONPATTRO is an intravenously administered RNAi therapeutic targeting transthyretin (TTR). It is designed to target and silence TTR messenger RNA, thereby reducing the production of TTR protein before it is made. Reducing the pathogenic protein leads to a reduction in amyloid deposits in tissues. For more information about ONPATTRO, including full Prescribing Information, visit ONPATTRO.com.

About AMVUTTRA^® (vutrisiran)

AMVUTTRA^® (vutrisiran) is an RNAi therapeutic approved in the United States for the treatment of adults with hATTR amyloidosis with polyneuropathy. It is a double‑stranded small interfering RNA (siRNA) that targets mutant and wild‑type transthyretin (TTR) messenger RNA (mRNA). Using Alnylam’s Enhanced Stabilization Chemistry (ESC)-GalNAc-conjugate delivery platform, AMVUTTRA is designed for increased potency and high metabolic stability to allow for subcutaneous injection once every three months (quarterly). Results from the pivotal HELIOS-A Phase 3 study demonstrate AMVUTTRA rapidly reduces serum TTR levels, has the potential to reverse neuropathy impairment relative to baseline and improves other key measures of disease burden relative to external placebo in patients with the polyneuropathy of hATTR amyloidosis. For more information about AMVUTTRA, including the full U.S. Prescribing Information, visit AMVUTTRA.com.

About GIVLAARI^® (givosiran)

GIVLAARI (givosiran) is an RNAi therapeutic targeting aminolevulinic acid synthase 1 (ALAS1) approved in the United States and Brazil for the treatment of adults with acute hepatic porphyria (AHP). GIVLAARI is also approved in the European Union for the treatment of AHP in adults and adolescents aged 12 years and older. In the pivotal study, givosiran was shown to significantly reduce the rate of porphyria attacks that required hospitalizations, urgent healthcare visits or intravenous hemin administration at home compared to placebo. GIVLAARI is Alnylam’s first commercially available therapeutic based on its Enhanced Stabilization Chemistry ESC-GalNAc conjugate technology to increase potency and durability. GIVLAARI is administered via subcutaneous injection once monthly at a dose based on actual body weight and should be administered by a healthcare professional. GIVLAARI works by specifically reducing elevated levels of ALAS1 messenger RNA (mRNA), leading to reduction of toxins associated with attacks and other disease manifestations of AHP. For more information about GIVLAARI, including the full U.S. Prescribing Information, visit GIVLAARI.com.

About OXLUMO^® (lumasiran)

OXLUMO (lumasiran) is an RNAi therapeutic targeting hydroxyacid oxidase 1 (HAO1). HAO1 encodes glycolate oxidase (GO). Thus, by silencing HAO1 and depleting the GO enzyme, OXLUMO inhibits production of oxalate – the metabolite that directly contributes to the pathophysiology of PH1. OXLUMO utilizes Alnylam’s Enhanced Stabilization Chemistry (ESC)-GalNAc-conjugate technology, which enables subcutaneous dosing with increased potency and durability and a wide therapeutic index. OXLUMO has received regulatory approvals from the U.S. Food and Drug Administration (FDA) for the treatment of primary hyperoxaluria type 1 (PH1) to lower urinary and plasma oxalate levels in pediatric and adult patients and from the European Medicines Agency (EMA) for the treatment of PH1 in all age groups. In the pivotal ILLUMINATE-A study, OXLUMO was shown to significantly reduce levels of urinary oxalate relative to placebo, with the majority of patients reaching normal or near-normal levels. In the ILLUMINATE-B pediatric Phase 3 study, OXLUMO demonstrated an efficacy and safety profile consistent to that observed in ILLUMINATE-A. In the ILLUMINATE-C study, OXLUMO resulted in substantial reductions in plasma oxalate in patients with advanced PH1. Across all three studies, injection site reactions (ISRs) were the most common drug-related adverse reaction. OXLUMO is administered via subcutaneous injection once monthly for three months, then once quarterly beginning one month after the last loading dose at a dose based on actual body weight. For patients who weigh less than 10 kg, ongoing dosing remains monthly. OXLUMO should be administered by a healthcare professional. For more information about OXLUMO, including the full U.S. Prescribing Information, visit OXLUMO.com.

About LNP Technology

Alnylam has licenses to Arbutus Biopharma LNP intellectual property for use in RNAi therapeutic products using LNP technology.

About RNAi

RNAi (RNA interference) is a natural cellular process of gene silencing that represents one of the most promising and rapidly advancing frontiers in biology and drug development today. Its discovery has been heralded as “a major scientific breakthrough that happens once every decade or so,” and was recognized with the award of the 2006 Nobel Prize for Physiology or Medicine. By harnessing the natural biological process of RNAi occurring in our cells, a new class of medicines known as RNAi therapeutics is now a reality. Small interfering RNA (siRNA), the molecules that mediate RNAi and comprise Alnylam's RNAi therapeutic platform, function upstream of today’s medicines by potently silencing messenger RNA (mRNA) – the genetic precursors – that encode for disease-causing or disease pathway proteins, thus preventing them from being made. This is a revolutionary approach with the potential to transform the care of patients with genetic and other diseases.

About Alnylam Pharmaceuticals

Alnylam Pharmaceuticals (Nasdaq: ALNY) has led the translation of RNA interference (RNAi) into a whole new class of innovative medicines with the potential to transform the lives of people afflicted with rare and prevalent diseases with unmet need.
